Consider the compound shown below: Which of the following statements is correct regarding this compound?
Options
- AIt neither forms a dioxime nor gives a positive iodoform test.
- BIt both forms a dioxime and gives a positive iodoform test.
- CIt forms a dioxime.
- DIt gives a positive iodoform test.
Correct answer
A. It neither forms a dioxime nor gives a positive iodoform test.
Step-by-step solution
The given compound is ethyl acetoacetate, which contains a ketone group and an ester group. Reaction with hydroxylamine ( NH ₂ OH ): Hydroxylamine reacts with aldehydes and ketones to form oximes, but it does not react with esters under normal conditions. Since the compound has only one ketone group, it forms a mono-oxime, not a dioxime. Iodoform test ( I ₂/ NaOH ): Although the compound contains a CH ₃ CO - group, it also has an active methylene ( - CH ₂- ) group flanked by two carbonyls. The protons of the active
